【问题描述】:
我不确定为什么会收到错误消息。这里有意见和好处
from polls.models import Word, Results
def detail(request):
q = Word(type="How do you like")
q.save()
Word.objects.get(pk=1)
q.score_set.create(score=5)
q.score_set.create(score=4)
q.score_set.create(score=3)
q.score_set.create(score=2)
q.score_set.create(score=1)
return render_to_response('/$')
模型.py
from django.db import models
class Word(models.Model):
type = models.CharField(max_length=200)
def __unicode__(self):
return self.type
class Results(models.Model):
word = models.ForeignKey(Word)
score = models.IntegerField()
def __unicode__(self):
return self.score
错误:

【问题讨论】:
-
请发布您的实际代码。对于您在这里的模型,
Word没有score_set- 它有results_set。 -
不确定您所说的实际代码是什么意思。我有模型、视图、url 和模板。我还没有使用 url 和模板,所以我只是发布了模型和视图。
-
关键是这段代码会给你显示的那个不同的错误——它会给
score_set一个AttributeError。 -
我发布的错误来自此代码。我刚刚又跑了一遍。剩下的代码你会说什么?
-
只是好奇,为什么要在代码的第 6 行执行此查询?
